JAPAN ELECTRIC SINGEING MACHINE Application filed August 11, 1928, Serial No. 299,016, and in Japan July 7, 1928.

This invention relates to improvements in the electric singeing machine.

The characteristic feature of this invention is the provision of a number of singeing elements and a number of guide plates interposed between the singeing elements, which is composed of the parallel electric wires connected in series. The cloth to be singed passes over the top faces of the guide plates leaving a desired'gap between the cloth and the electric wire and the height of the guide plates may be regulated at will and all the electric wires are equally stretched by the special terminal.

When the cloth-stopped by some source such as obstacle in the prime mover, it may be parted from the singer, which at the same I time, may be covered by a covering plate.

The objects of this invention are to regulate easily the gap between the cloth and the electric wire, to compensate easily the wear of the guide plates, to renew the guide plate independently from other parts and to protect the cloth from burning, when the cloth is stopped by the double safety device.

Fig. 1 is a perspective view of this singeing machine.

Fig. 2 is a plan of the cloth and the singer.

Fig. 3 is a sectional elevation of that shown in Fig. 2.

Fig; 4 is a side view showing the relation of the parallelogram, the singer and the covering plate.

Fig. 5 is a perspective view thereof.

Fig. 6 is a perspective view of the terminal and Fig. 7 is a detail of the guide plate.

In the drawings 1 designates the side standards. The singer 3 is mounted upon a shelf 4 spanned on the cross bars 2 of the side standar s.

The singeing element consists of the electric wire 5, the dish shaped insu1ator 6 supporting the wire and the fixer 7, fixing the,

and the guide plates is called the singer 3.

The gap between the electric wire and the cloth must be kept constant. For this purpose the guide plates 8 have the screw rods 9 at the bottom and the rods pass through the holes in the shelf and the nuts 11 are screwed thereon. The set screws 12 are screwed on the screw holes of the guide plate 4 and the top abut the bottom face of the guide plate 8, as shown in Fig. 7. The height of the guide plate may be regulated by the set screw 12 and it may be fastened in a desirable height by the nut 11. By this means the wearing of the guide plate may be compensated and the guideplate itself y be renewed easily independentlyfrom the other parts of the machine. Many pair of the guide plates and singeing element are provided. The cloth is nappcd by the friction With the guide plate, hence the nap napped by one guide plate is singed by the next singeing element, thus the many pair singe the cloth completely.

In the machine illustrated, there are four pair of the guide plates and the singeing elements. The electric wires 5 of these elements are connected in series with the out lines 13 by the terminals 14. When two electric wires arranged parallelly are connected to a common terminal, the gap between the cloth and the electric wire may be changed at some point by unequal elongation of the wires When heated. Such defect arises when one of the wires has been renewed.

To eliminate such defect, the terminal 15 has the special construction as shown in Fig. 6. The electric wires are twisted and con-- neeted to the terminal 15, which has a truncated cone 16 on the bottom. The cone 16 engages in the dove tail groove on the guide 17. The terminal 15 is normally pulled by the spring 18 to stretch the Wires when elon gated equally.

If one of the wires elongates more than the other, then theterminal 15 rotates in the dove tail groove and the more elongated wire is more stretched than another, thus both wires are kept in straight lines always. 7

Two shafts 20, 21 are journaled on the upper cross bars 19 of the side standards 2. The shaft 20 has two hanging arms 22, the

v 21 as shown in Fig. 5.

lower ends of which hold the guide shaft 24. The shaft 21 has two hanging arms 23, the lower ends of which hold the guide shaft 25. The guide shaft 24 is connected to the guide shaft 25 by the connecting rod 26, thus'the arm 22, the connecting rod 26 and the arm 23 form a linkage as shown in Fig. 4 and the cloth 10 passes over the shafts 20, 24, 25 and Those shafts may be covered by the rollers made of desirable material.

A notch 27 is provided on the lower end of one arm, for example the arm 22 and the hook at one arm of the bell crank lever 29 engages with the notch 27. The lever 29 is mounted on the shaft 28 journaled between.

the cross bars 2 anda pull rod 30 is connected to another arm of the lever 29.

The upper end of the arm 22 has a horizontal rod 31, to which a weight 32 is mounted.

The lever 34 is mounted on the shaft 33, and one arm of the lever has the covering plate 35, curved to cover the, singer 3. The

outer end of the covering plate .has the fork 36, which en ages normally with the shaft 24.

Another rm of the lever 34 is connected to a fixed part of the machine by the spring 37.

The action of this safety device is as follows: v

If the cloth stopped by some source such as an obstacle of the prime mover, the pull rod, 30 is to be pulled, then the hook of the lever 29 disengages from the notch 27 and the linkage 22, 26, 23 changes its position from that illustrated by the full line in Fig. 4 unto that shown by the dotted line by the action of the weight 32. There is no change in the length of the cloth betweenthe shafts 20 and .21, because the cloth is guided by the linkage.

At the same time, the fork 36 disen'gages from the shaft 24 and the covering plate 35 movesto the position tocover the singer by the action of the spring 37, thus .the cloth is separated entirely from the singer.

The pull rod 30 may be modified if desired and it will be more convenient to connect such startin means to the sto motiogloif1 the cloth.

As escribed above, 's mac e has the double safety devices, that is to say, one the parting of the cloth itself from the singer and another the covering of the singer by the covering plate, hence the burning of. cloth is entirely avoided although the cloth has been sto ed by any source.

ving now particularly described and names to this 3. An electric singeing machine, as claimed in claim 1, including a base plate supporting the singeing elements and guide plates and having a dovetail groove, a truncated cone mounted for rotary and longitudinal movement in said groove, said terminal connected to two of said parallel electric wires, substantially as described.

4. An electric singeing machine, as claimed in claim 1, including four shafts, a plurality of arms and a rod to form a linkage, said rods being adapted to guide the cloth over said singeing elements, and a weight for said linkage to lift one of said shafts and separate the cloth from the singeing elements.

5. An electric singeing machine, as claimed.

in claim 1, including a guide shaft for the cloth, a plate to cover the singeing elements, the plate being held in normal engagement with one of said shafts, and away from the elements, a spring tending to move said plate to cover the singeing elements, and means to move the shaft to release the cover to the acv tion of the spring.

In testimony whereof, we have signed our ecification at Kobe, Japan, this 17th day 0 July, 1928.
